Novel 5,6-dihydro-2-(substituted phenyl)-1,2,4-triazine-3,5(2H, 4H)-diones which are effective in destroying or preventing the growth of Protozoa in subjects suffering from such Protozoa.
it urgent to develop a more simple and practical protocol. To confront the limitations and enrich Minisci-type chemistry, herein, we disclose a photocatalytic Minisci-type multicomponent reaction for the synthesis of various (halo)alkyl BCP-aryls using [1.1.1]propellane, alkyl halides, and unfunctionalized heteroarenes as starting materials. Diverse kinds of unfunctionalized heteroarenes and alkyl
